This double nut ball screw control kit is designed for 20mm diameter 2020series systems and offers a lead for faster axis travel. It belongs to the SFE2020 line and includes a DSG2020 nut housing, BKBF15 end supports, and a coupling, with a total length of 750mm. The dualnut design allows preload adjustment for smoother motion and improved rigidity, making it suitable for demanding linear motion tasks. Key benefits Faster travel per turn: large lead ball screw enables quicker axis movement, increasing productivity in machining and automation tasks. Reduced backlash through a dualnut design: preload adjustment helps achieve smoother, more precise motion and better repeatability. Complete kit for immediate installation: includes DSG2020 nut housing, BKBF15 end supports, and a coupling, minimizing sourcing steps. 750mm length for versatile applications: supports mediumlength axes while maintaining compact overall footprint. Reliable 20mm diameter system: compatible with common 20mm ball screw configurations, offering a balance of strength and applicability. Key attributes Diameter: 20 mm Lead: large lead configuration (SFE2020 series) Length: 750 mm Nut housing: DSG2020 End supports: BKBF15 Coupling: included Type: double nut ball screw kit Application focus: precise linear motion for machine control and automation Compatibility and scope Designed for 20mm 2020series ball screw installations, compatible with SFE2020based setups. Includes essential components for mounting and support, reducing assembly complexity and alignment issues. Use cases CNC machines and milling routers: upgrade an X or Y axis with smoother, faster linear motion and tighter performance through dualnut preload. Automated production or packaging lines: improve throughput on short to mediumlength axes by leveraging the larger lead for quicker positioning. Custom automation projects or gantry systems: implement a reliable 20mm ball screw axis with end supports and coupling for robust, repeatable movement.
